Well, it was a tough one today. I have to say I had some lower back problems today. When I warmed up this morning I felt something. I wasn't sure if I would be able to play or not. I tried, but you see the result. I couldn't do that much out there - I couldn't serve, couldn't return, and couldn't run to the ball. So it was definitely not my best day. I hope I can recover soon and come back stronger... - See more at: http://www.wtatennis.com/news/articl....assisIgj.dpuf
